' WHEEL SPINDLE AND AxLE..

Specication of Letters Patent.

Patented June 4, 1907.

\ Application filed April 9, 1906. Serial No. 310.729.

.To all wil/m, it may concern:

Be it known that I, THOMAS J .Y LINDSAY, a

i citizen of the United States, residing at Infor the driving wheels of automobiles, the

dianapolis, /in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Wheel Spindles and Axles, of which the following is a specification.

The object of my invention is to produce a wheel spindle and axle,` especially designed construction being such that the main portion of the axle may be made from commercial stock, suc-h as a standard I-beam, While the spindle pro er may be made from a drop forging or stee casting which may be easily machined.

A further object of my invention is to assoi ciate with my improved spindle a brake structure of such form as to be readily applied to and withdrawn from the driven member.

The accompanying drawings illustrate my Invention:

Figure 1 is a vertical axial section of my improved spindle and brake with. a driving wheel and sprocket ap lied thereto; Fig. 2 a section on line 2 2 of Flig'. 1; Fig. 3 a section on line 3 3 of Fig. 1 on a small scale, Fig. 4 an elevation of the brake-ring su port with the wheel and brake cup remove and Fig. 5 a perspective of the spindle structure.

In the drawings, 1 0 indicates the spindle end provided with portions 11 and 12 adapted to receive the bearing cones yof any desired form of bearing to receive the hub ofawheel 13. The spindle 10 terminates at one end in an intermediate. preferably cylindrical body 14 which is diametrically slotted at 14 and each portion terminates in a finger 15.. The inner faces 15 of the portions 15 form continuations of the sides of the diametrical slot.

14. The top and bottom edges 15" of each finger 15 are also accurately-machined to inprojecting portion of the web 16" of the I- earn, this web fitting the diametricalslot of the body 14 of the spindle and radially from opposite sides of sai clearly shown in Fig. l.

Fitted upon body 14- of the spindle is the hub 18 of a brake-supporting disk 18, the hub 18 being provided with keyways 18 to receive the projecting portions of the I- projecting body, as

said ears, the spindle structure and web of the I-beam axle. Asecond bolt 20 may be assed through ingers 15 and the web of the -beam. The projecting portion of web 16 maybe narrowed to the diameter of the portion 14, and the ears 19 be relied upon to prevent rotation of the brake-sup orting disk but I prefer the construction sIiown in the drawings.

The driving sprocket 25 is carried by a brake cu 26 which may be attached to the hub of W eel 13 by bolts 27 in a well known manner.

My im roved brake consists of a `metallic rin 30 W ch, in its middle portion, is slotted to orrn a air of parallel, axially-se arat-ed plates 30 etween which I mount t e stem of a semiannular wooden block 31 which is T-shaped in cross section, the head of the T overlapping the external circumferences of the lates 30, as shown in Fig. 2.

T e ring 30 is split at one point and its ends overlapped, as shown in Fig. 4, and the overla ping ends `are'perforated by bearings 35 ancl)35 respectively which are preferab y arranged with their axes in a plane radially of the axis of the spindle. The bearings 35 and 35 are adapted to receive the parallel pins 36 and 36 respectively which are carv pins 36 and 36 and When-the parts are in normal position, Yas shown in Fig. 4, the

`brake ring has all of its friction portion out of engagement with the interior of thecup 26,

but when the lever 39 is moved in the direction indicated by the arrow in Fig. 4 the brake ring is expanded and will come rst into engagement with the cup 26 at points near the pins 36 and 36 but, being free to shift transversely ofthe axis of the spindle there will be a slight movement of the ring roo relative to the-pin 41 so .that the ring will seat firmly along its entire friction surface. When the parts are returned to 1n1t1al position a relative movement of the ring uponv pin 41 will be in the reverse direction and the entire friction surface of t'he ring will be' drawn away'from the cup.

I claim as my invention:

1. The combination, with an I-beam axle vhaving its web projected at the end, of a wheel spindle having a bifurcated inner end adapted to embrace the web of the axle and projected between the flanges thereof', a

`brake-supporting member mounted upon the spindle and provided with keyways adapted to receive the projected web of the axle, means for securing the spindle and brakesupport against axial displacement, and a bra e carried by said brake-support.

' structure against longitudinal displacement,

3. The combination, with an axle structure having a mediall web and overhanging flanges, of a wheel-spindle havingan inner end fitted between said overhanging flanges, and the projected end of the medial web of the axle structure projected radially from the spindle, a brake support mounted on the spindle and having a keyway adapted to receive the radially projecting portion ofthe axial web, means for securing the spindle and brake-support against axial displacement, and a brake carried by said brake-su port.

4.. The combination, with anax e structure having a medial web and overhanging flanges, of a wheel spindle having a spindle portion at one end, an intermediate body, and' a pair yof parallel fingers adapted to embrace the medial web of the axle structure, means for holding the spindle structure on the axle a brake-supporting member mounted on the medial portion of the spindle structure, and a brake carried by said brake-support.

5. The combination, with an axle structure havinga medial web and overhanging flanges, of a wheel spindle havin a spindle portion at one end, an intermeiate body, and a pair of parallel :fin ers ada ted to embrace the medial web o the ax e structure and lie between the overhangi flanges of the axle structure, means forniolding the spindle structure onl the axle structure against longitudinal displacement, a brakesupporting member mounted on the medial portion of the spindle structureand having an ear projecting alon side one of the web embracmg fingers, an a brake carried by said brake-support.

6. The combination, with an axle structure having a medial web and overhanging flanges, of a wheel spindle having a spindle portion at one end, an intermediate body, and a pair of parallel fingers adapted to embrace the medial web of the axle structure and lie between the overhanging flanges of the axle structure, means for holding the spindle structure on the axle structure against longitudinal displacement, a brakesupporting member mounted on the medial portion of the spindle structure', a brake carried by said brake-support, a rock-shaft j ourrialed in the brake-support and provided with a pair of pins .para'llelfwith the rockshaft, a split brake ring having-'its ends journaled upon said parallel pins and supported thereby, and interengaglng means between the brake ring against swing but permitting radial movement thereof.
